I like 9443cf props. They are the same profile as the stock dji props, but they are stiffer and don't bend in my box. I've tried all kinds of props including 3 bladed ones, and I keep coming back to the 9443s. All props have to be balanced, but I've found a huge difference in motor temperature after a test flight. In my experience, the stock dji props tend to increase jello in my video, and I get much more responsive sticks with the cf props.
